168 Details of Borings in Search of Fresh Water. 
1. Section afforded by borings from 3 d December 1804 to Ath January 1805. 
Feet inclusive. 
0 to 9 Surface mould, bricks, and rubbish. 
10 — 1 1 A. layer of sand. 
12 — 57 Sandy blue clays; from 36 to 40 feet mixed with decayed wood; the last 
3 feet light brown clay. 
58 — 62 Hard sea green clay, mixed with small stones. (Qu. Kunkur ?) 
63 — 70 Yellow clays, hard, and latterly very hard. 
71 — 75 Hard kunkur and sand. 
Remarks. The borings for the first 32 feet were taken parallel to a well of that 
depth, and afterwards continued in it. 
On the 29th of December, the water in the well stood at 5 feet 3 inches, and at 
noon at 2 feet 3 inches. On the 30th December the water began to rise, and con- 
tinued to increase until it attained the height of 13 feet within the well. 
This water, taken from the well on the 16th January 1805, was analysed by Dr. 
Hunter. 
The water never rose beyond the height mentioned, and was then on a level with 
the water in two adjoining wells ; showing that the salt waters of the three had 
their origin in the same springs. 
2. Section afforded by borings from August to September 1805. 
Feet inclusive. 
0 to 11 Two feet of bricks and rubbish, and 4 feet of brown mould, were follow- 
ed by 5 feet of yellowish clay, mixed with sand. 
12 — 15 A stratum of soft white sand. 
16 — 62 A series of hard blue and blackish clays, mixed with roots, rotten and 
charred wood, and latterly changing to whitish clays ; at 56 feet kun- 
kur. 
63 — 71 Stiff, very bard, white and yellow clays, streaked occasionally with 
green, containing some kunkur. 
72 — 96 Beds of yellow sand, and yellow clay mixed with sand. 
97 — 118 Fine, hard, yellow-ochre coloured clay, intermixed with kunkur ; the 
latter 3 feet, very hard. 
119 Coarsegrained sand, the soil very hard ; the borer broke, and was not 
recovered. 
Remarks. At 70 feet the water from the borer was brackish. At 81 feet and at 
101 feet, the rods were brought np nearly dry. A well of tiles had been sunk, 
round the borer, for the first 30 feet, and the water rose in it to within 7 feet of 
the surface ; fully 4 feet of the ground, at this place, wa:; artificial, above the 
general level of t he country. During the whole dry season the water only subsided, 
in this well, 3 feet, and was on the 3d June only 10 feet below the surface; whilst 
the water in wells at a little distance was 30 feet below it. 
3. Section from 1 Gt/i December 1805, to 1 \tk February 1806.

feet of the surface and were well tasted.
